Help Design a New Cryptography API for PHP 7.1

TL;DR, make this part of PHP 7.1:

$cipher = new Php\Crypto\Symmetric([
'driver' => 'openssl'
]);
$key = $cipher->deriveKey(
$someUserProvidedPasswordString,
$someHardCodedSalt
);
$encrypted = $cipher->encrypt($message, $key);

I'm developing a userland prototype in PHP here, so hopefully anyone
can join in even if you're not fluent in C:
https://github.com/paragonie/pco_prototype

Once we're happy with how the API functions, and what the
default/allowed parameters will be for each driver, we can start
writing the PHP extension and move forward with the RFC to merge it.

Here's an overview of the project:

• The API (what we're discussing)
• The drivers (we don't develop these)
  • Libsodium
  • OpenSSL
  • Room to grow in case we need to adopt for a post-quantum
    cryptography library
